具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
应理解，在本申请实施例中，各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
应理解，在本申请的实施例中，对术语进行的编号一般是为了区分方便而进行的描述，编号并不意味着该术语存在顺序或者优先级的区别，比如“第一相关矩阵信息”和“第二相关矩阵信息”，其中的“第一”和“第二”，通常只用于区分这两组信息，而不应对本申请实施例的实施过程构成限定。
应理解，在本申请实施例中，“至少一个”是指一个或者多个，“多个”是指两个或两个以 上。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
应理解，在本申请实施例中，术语“***”和“网络”在本文中常被可互换使用。
应理解，在本申请实施例中，术语“和/或”，通常用于描述关联对象之间的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。应理解，在本申请实施例中出现的字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例提供的方法及装置可以应用于通信***中。图1是本申请的实施例应用的通信***100的架构示意图。如图1所示，该通信***包括无线接入网110和核心网120，可选的，通信***100还可以包括互联网130。其中，无线接入网110可以包括至少一个无线接入网设备(如图1中的111a和111b)，还可以包括至少一个终端(如图1中的112a-112j)。终端通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端和终端之间以及无线接入网设备和无线接入网设备之间可以通过有线或无线的方式相互连接。图1只是示意图，该通信***中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。
无线接入网设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、第五代(5th generation，5G)移动通信***中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信***中的下一代基站、未来移动通信***中的基站或WiFi***中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。无线接入网设备可以是宏基站(如图1中的111a)，也可以是微基站或室内站(如图1中的111b)，还可以是中继节点或施主节点等。可以理解，本申请中的无线接入网设备的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平台)上实例化的虚拟化功能来实现。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以基站作为无线接入网设备的例子进行描述。
终端也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。
基站和终端可以是固定位置的，也可以是可移动的。基站和终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对基站和终端的应用场景不做限定。
基站和终端的角色可以是相对的，例如，图1中的直升机或无人机112i可以被配置成移动基站，对于那些通过112i接入到无线接入网110的终端112j来说，终端112i是基站；但对于基站111a来说，112i是终端，即111a与112i之间是通过无线空口协议进行通信的。当然，111a与112i之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于111a来说，112i也是基站。因此，基站和终端都可以统一称为通信装置，图1中的111a和111b可以称为具有基站功能的通信装置，图1中的112a-112j可以称为具有终端功能的通信装置。
基站和终端之间、基站和基站之间、终端和终端之间可以通过授权频谱进行通信，也可以通过免授权频谱进行通信，也可以同时通过授权频谱和免授权频谱进行通信；可以通过6千兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。
在本申请的实施例中，基站的功能也可以由基站中的模块(如芯片)来执行，也可以由包含有基站功能的控制子***来执行。这里的包含有基站功能的控制子***可以是智能电网、工业控制、智能交通、智慧城市等上述终端的应用场景中的控制中心。终端的功能也可以由终端中的模块(如芯片或调制解调器)来执行，也可以由包含有终端功能的装置来执行。
在本申请中，基站向终端发送下行信号或下行信息，下行信息承载在下行信道上；终端向基站发送上行信号或上行信息，上行信息承载在上行信道上。
可以理解，随着网络的演进，上述网元的名称可能发生变化，网元的功能也可能发生合并、分离、甚至改变，但这些变化并不意味着脱离了本申请方案的适用范围。
单小区接收时，接入网设备架构多采用集中式架构对数据进行处理。该架构需要将所有的天线数据集中起来，除了正常的数据处理外还需要额外数据汇总处理。当天线不断增加时，集中式处理架构不仅使数据处理的复杂度呈指数倍地快速增加，还使汇总数据的总线带宽迅速增加，进而加大接入网设备芯片本身的设计困难。同时，由于接入网设备需要支撑多种不同天线规模场景的应用，集中式处理带来的动态链接带宽需求使接入网设备需要根据不同的连接形态设计不同的连接方案，引入额外的连接成本。因此，随着未来更大规模天线的应用，集中式处理可能会成为瓶颈。
分布式接入网设备处理方案主要是将天线分簇，每簇天线数据处理后再与其他簇的天线数据进行融合或交互，待所有簇的数据都进行融合或者完成交互后，再输出最终数据结果，当前的分布式接入网设备处理方案虽然可以缓解数据处理的复杂度，但是为了保证数据处理性能，当前的分布式接入网设备处理方案会存在环路和耦合，也可能存在数据迭代处理，这样会引入额外的时延和缓存以及额外的数据处理复杂度。
因此如何设计一种可以解决随着天线增加数据处理复杂度变高，传输数据总线带宽变宽，数据处理成本增加等问题的数据处理方法，成为亟待解决的问题。
本申请提供了一种数据处理的方法及装置，用于解决随着天线增加数据处理复杂度高，传输数据总线带宽变宽，数据处理成本增加等问题。
